overflow: scroll;
-webkit-overflow-scrolling: touch;
As far i can tell this is not implemented yet in ST2.0.

Have you worked on this "native" css scroll for lists ? Do you plan to ?
Heard that it could be somehow bugged in IOS5, so i'm wondering where are you on this.

I think it would be great as i am not satisfied with the scrolling experience on an iPhone4 running IOS5.

On a javascript-only solution :

I've been quite impressed by J.Hewitt is really smooth on my device.

Anything good to extract from this?
Do you think it could be easy to somehow override Ext.List with an Ext.ScrollabilityList ? How should i start ? extending Ext.List or creating a new DataView ?
